Light weight aggregate concrete block:

Leca concrete is made by mixing of Leca aggregates, cement and Water. Adding sand into the mixture reduces the porous and Makes the concrete with Smoother surface. Adding of Sand decreases the volume of air in concrete and increases concrete strength.

This kind of block (with addition of sand) is called medium weight concrete block. When fine light weight aggregate is replaced by sand, workability goes high, water-cement Ratio decreases, and the strength of concrete increases.

Using Leca for non-bearing walls will reduce concrete weight and the thermal conductivity. With these particular and above specifications for Leca aggregates, following advantages can be expected from Leca Concrete:

Lower weight

Easy transportation

Reduction of manpower and construction time for its lightness and easy- applying

Easy for plastering on cellular texture and rough surface of the block

Strength against imposed pressures

Durable thermal insulation since the inside porous texture of aggregates and the air existing inside and among the aggregates
